The results of a post-mortem examination will be crucial in determining whether Mr Schwartz will face any charges over the death of a 35-year-old intruder inside his family’s home in Sydney’s southwest on Sunday.

The 38-year-old chef remains free on bail ahead of his November trial for the murder of Ricky Slater-Dickson in the early hours of March 26, 2016.

Mr Batterham allegedly found Mr Slater-Dickson in his young daughter’s bedroom before chasing him down and restraining him. Mr Slater-Dickson lost consciousness and later died in hospital after his life support was switched off.

“People are entitled to (defend) their home, they’re entitled to use reasonable force to protect themselves and their property,” Camden Police Chief Inspector Shane Woolbank told reporters at a press conference.

“The autopsy will determine hopefully his cause of death, which will be a significant factor in where we take this investigation.”

The father has been lauded on social media as a “hero” for defending his family.

Whether or not Mr Schwartz faces charges will hinge on the results of the post-mortem examination into the 35-year-old’s death.

If the victim was found to have died as a result of excessive force, Mr Schwartz could be charged with murder or manslaughter.

Residents reported having seen the man wandering around the area barefoot hours before his confrontation with Mr Schwartz.

Inspector Woolbank told reporters the man had “a ginger-like moustache and beard” and was dressed in a “blue sleeveless top and grey Nike training shorts”.

“He also had two distinct tattoos, one on the left upper inside of his arm, but that tattoo was not in English,” Insp Woolbank said.

A tattoo on his chest began with the words “True to ourself”, he said.

Neighbour Domenic Lombardo told The Daily Telegraph he saw a man run through a neighbouring building site around the time of the home invasion, describing him as “breathing heavy and mumbling to himself’’.
